Anyone know if there's something like this I could use on my Debian server?

It's all very well doing it on our SSDs, but if you think about it they're the drives that need it the least. Where it would really make a big difference would be my 8 drive RAID6 array Debian server which has 8GB of memory and never uses more than 300MB There's no reason at all I couldn't fire 6GB of memory at it and it should speed up things on the network rather greatly.

I do think I'l run it on my SSDs though, all the same
